Flat Architecture In The Enterprise Network Application

Along with the development of the times, in addition to high performance, high reliability, high expansion, high safety and easy management, enterprise network also has a higher performance in order to meet the needs of the Internet. Enterprise network should not only provide the services of distributed database, E-mail system, Web sites, file transfer, fax/print, financial and accounting, but also carry the services of IP voice, video broadcasting, electronic transactions, video conference, engineering design, order entry/tracking according to the quality of service (QoS).Because the equipment performance of existing enterprise network has been unable to meet the needs of the network, the replacement of equipment is the only way to solve the network bottleneck. The urgent problem is how to meet the demand of the development of modern enterprise network and future network, at the same time reduce the cost of corporate reconstruction. The main works of the thesis are as follows:(1)At present, most of the enterprise network adopts the model of three-tier logical architecture, the kernel layer, convergence layer and access layer. Using this architecture must replace a large number of equipment of kernel layer and convergence layer to meet the demand of the development of modern network. The two layer logic structure of the kernel layer and the service control layer, namely the flat architecture, has good scalability. The network upgrading and transformation only needs to replace the kernel layer equipment, simplifying the network upgrade process, saving a large amount of construction funds.(2)Taking a university as an example, this thesis introduces the problem which this university is faced with at present in detail. According to the characteristics of the flat structure, this paper put forward the reform scheme of adopting the flat structure, building the campus network of high performance, precise and easy management. Further proving the feasibility of this scheme and providing a detailed description of the plan implementation process.(3) The thesis details the logic design process, and analyzes the physical design of the equipment performance requirements, demonstrates the advantage of using routers of core equipment based on the principle of network design. Finally, the thesis explains the implementation principle of reconstruction project of campus network and detailed configuration of each device, at the same time shows the preliminary test results of the scheme...
